' Application October 16 1942, Serial No. 462,246 I 9 Claims; (Cl. $8 -89) My invention relates-to a cleanout plug rneans to be used inconnection with plumbing-appa-' ratus and the objectsof my invention are:

"First, to-provide a cleanout plug means which eliminates the necessity for the conventional bronze screw plug; 1 I

Second; to provide a cleanout'plug means of this class which may be used in connection with acleanout fitting member or with a Y-fitting or with any other plumbing fittings where it might be required with slight change in the fitting;

Third, to provide a cleanout'plug means of this class whichm'ay be readily and easilyv released after it has stOOd over a long period of time; Fourth, to, provide a cleanout. plug means of this class in which the ceiling of the 'plug is quickly and easily effected;

Fifth; ,to provide a cleanout' plug means of tance from its open end and is provided with two inwardly extending fiange' portions lb. and I0,

' the lower sides of which are providedwith in 'provided with two. extended flange portions 2b clined surfaces so that when turning the clamping member 2 therein, the clamping member 2 is forced downwardly when turned in one direction and upwardly when turned in the opposite direction.

The clamping member 2 is provided with a wrench receiving portion 2a which extends upwardly from the main'portion thereof and it is and which are "inclined surfaces and arranged to engage the lower surfaces of the portions lb and lo of the fitting I. This plug member is provided with a central recessed portion 2d'which this class which is very simple and economical of construction, easy to 'operate,}efficientin'its ac tion and which will not readily deteriorate or I get outoforder. v With, these andotherobjects in view as will appear hereinafter, my invention consists of certain novel features of construction,combination and arrangement of parts and portions asjwill be hereinafter described indetailand particularly set forth in the appended claims, reference being had'to .the accompanying drawings, and to the characters of reference thereon whichform a part of this application in whichz- 1 .Figure 1 is a top or plan view; of a Y-fitting with my c1eanout,plug' ,r neans in connection therewith; Fig; 2 is a partial elevational andsec tional view. of the fitting shown fragmentarily;

the fitting as shown in Fig. 2in a s1i'ghtlyfmodi-' fied form; Fig. 6 is a top or plan view of a conventional fitting hub showing my cleanout plug means in modified form from that of ,Figs. 1 to 5 inclusive; Fig. 7 is a frag'mentary side elevational view thereof; FigQfljis a sectional view thereof taken from the line 8 80f Fig. 6fand Fig. 9 is a sectional view atright angles theretotaken from the line 9-9 ofiFigyfi. "i I I Similar characters of reference refer'to similar parts and portions throughout theseveral views bf the drawings. v v n 'In the preferred. form of construction shown in Figs. 1 to 4 inclusive, the fitting member I is pref- "erably a Y-fitting but the same structure is applicable to a cleanout fitting. This fitting ispro- 'vided with a ledge la on its'interior some disis adapted to engage a central upwardly extending lug portion3aof the plug member 3. This plug. member 3 is' circular and arranged to fit loosely in the interior of the fitting I above the ledge la and is providedwith an annulargroove 3b near its periphery in which is mounted an annular lead sealing member 4 which is adapted to rest on the upper side of the ledge Id of the fitting I, as shown best in Fig. 2 of the drawings.

' This member 3 is provided with a downwardly position;

extending annular flange 30 which extends down on the inner side of the ledge is when in sealing In the modified form cept that instead of the ledge la, the fitting is provided with a bulged'portion ld'providi'ng on its'inner'side a recessed portion 1e and the sealing member it rests on the lower side of the recess Is in the bulged portion, as shown in Fig. 5 of the drawings. a

.In' the modification shown in- Figs. 6 to 9v injclusive, there is provided the conventional fitting with a conventional female hub portion 5 which is provided with a conventional flange portion 5a and with the conventional annular side wall portion'5b upon which the sealing. ring@ rests. In i this case the plug member, which is designated 6, is of thisform. It' isprovided centrallywith a recess ea in which a lug "Ta is adapted to rest; as shown in Figs. 8 and 9 of the drawings. The

clamping member in this case consists of a fiat plate-like member 11) which is provided with a central hollow wrench receiving portion 10 and with opposed inclined portions Id and 'le at its opposite sides which are adapted, to engage clip members 8 which are provided with annular vertical portions 8a with inwardly turned flange portions ab with horizontal portions and with [A I of construction, shown in 'Fig. 5, the structure is the same throughoutexsecured in position in the member 3., The member 3 together with the sealing member 4 i then positioned within the open end of the fitting,

one side positioned in first and the other side following and placed down in position, as shown best in Fig. 2 of the drawings. Then the clamp member 2 is positioned so that the portions 217 and 2c are in open sides If and lg and pressed down until the recess 2d engages the lug portion 3a and the member 2 turned so that the members 21) and extend over the portions lb and lo which tightens the member 3 and compresses the sealing members against the ledge la. There is the same operation in the modified form shown in Fig. 5 except that the sealing member 4 engages the bulged side wall of the fitting i.

In the modified structure shown in Figs. 6 to 9, the members 8 are positioned over the upper edge of the fitting 5 in the position shown best in Fig. 8 of the drawings until the ledge portion 8!) passes the upper flange portion 5a of the fitting,

hich looks the member 8 in position on the fi*-- ting. Then the member 6 with the sealing member 4 is positioned to rest against the inclined portions 51) of the fitting 5 and the member I is in serted so that its long way is in the space between the members 8 and then turned with the lugs la positioned in the recess 6a, which tightens the member 6 and seals the sealing member 4 on the hub portion 5b.

Though I have shown and described a particular construction, combination and arrangement of parts and portions and certain modifications thereof, I do not wish to be limited to this particular construction, combination and arrangement nor to the modifications thereof, but desire to include in the scope of my invention the construction, combination and arrangement substantially as set forth in the appended claims.
